How to send data back to the datasource?

Posted By:      Posted Date: September 07, 2010    Points: 0   Category :ASP.Net
I have an ObjectDataSource which has two methods - GetData which gets data from the database and returns an array of Classes, and UpdateData which takes an array of Classes and updates the database.  The array of Classes contains sufficient information to allow UpdateData to work out what it needs to do.  So, to get an update to work, all I need to do is pass the [amended] array of Classes back to the ObjectDataSource via the UpdateData method. Then I have a control which inherits from DataBoundControl.  The control is happily using PerformSelect and PerformDataBinding to make the data available.  As it happens, I'm also implementing IScriptControl and throwing most of the data to the Browser as JSON for processing as a Javascript array.  I've got to the point where, on a PostBack, the data arrives back on the server and the control gets the array into the state where it is ready to update. Then, I need to pass the array of Classes over to the ObjectDataSource (the converse of the PerformSelect).  I was expecting to see a PerformUpdate or similar function within DataBoundControl.  At that point, I have juddered to a stop - and can't find anything which talks about how to get the data source to update. I'm, probably missing something obvious - and actually hope that I am! Thanks, Nick

Dynamic Data, Domain datasource, Poco and lookups


Mr. Edward,

Excuse my question but: it is necessary to involve in our projects something more than just Dynamic Data or should we make use of all other features available in VS2010 (which will make assume taht they had been left out of the Dynamic Data framework) like: wef, poco, azure, wcf, cloud, mvc, silverllight, ajax, odata, agile, workflow, etc.?

Sorry my ignorance, I'm just transcribing names as they come to my mind and of which I don't know anything about

Collaboration Data Objects: Send Microsoft Exchange Appointment Reminders to Your Pager Using CDO


Besides your typical e-mail services, Microsoft Exchange also provides the service infrastructure you need to build extensible knowledge and workflow management systems. Understanding Collaboration Data Objects (CDO) is the key to accessing these Exchange services for your own programs. With CDO you can automate tedious tasks and integrate information such as e-mail, calendars, and contacts with almost any application. This article explains how CDO enables you to access Exchange services, then walks you through a sample application that reads calendar events from an Exchange server and sends pager reminders to your users.

Errors in the back-end database access module. OLE DB reported an overflow of the data type for colu

Getting an error when processing a dimension, Errors in the back-end database access module. OLE DB reported an overflow of the data type for column 0. Errors in the OLAP storage engine: An error occurred while the 'xxxxxx' attribute of the 'Dim XXXXXX' dimension from the 'XXXXXXX' database was being processed. Content of this dimension is very similar to one that is processing no problem. The content of the dimension is one field only of type date.  The original content was imported through SSIS from a DB2 database on an iseries machine.  Thought a first the issue was because of the data contains some null values but the dimension the process OK also has some null  values.  The dimension that processes ok is also a single field of type date. Any help greatly appreciated, Roscoe

Sys.Data.DataContext.saveChanges method doesn't send update to server after DataServiceException ex

Hello,I have a page with a simple form that updates a single record in a table in my database.The database is accessed via WCF Data Services. To load and save data from/to the server, I usethe Sys.Data.DataContext object provided by the ASP.NET AJAX library. When the "save" button on theform is clicked, I use the saveChanges method of the Sys.Data.DataContext object to send all changes to the server.Also, at the server side, I use an interceptor that checks the "Price" fields of the record, and throws a DataServiceException exception when the contents of the field is a negative number.Both the JavaScript and the interceptor (in C#) are copied below.Here is the interesting thing:When I enter a negative price in the form, the interceptor throws the exception and my form shows an error message. Good.However, if I then make one of the other fields in the form a bit shorter (for example from "abcd" to "abc"),the saveChanges method doesn't send the data to the server. But it does call the success callback that I passed in to saveChanges, creating the impressionthat the data has been saved. This happens while the Price field is still negative. I used Fiddler to make sure thatno message is sent to the server. Also, the interceptor doesn't get executed.The weird thing is that if I make one of the fields a bit longer instead (for example &q

Passing data to the client and back - best way?

I'm ok (I think) with using a data bound Custom Control on the server to get hold of my data (it will be part of a larger dataset) and to ultimately pass updates to the database.  The bit I'm researching at the moment is passing that data to and from the client. One way to pass the data to the client is to use JSON within the Pageload event to construct a set of Javascript objects (one per row in the data).  Is that the best way, or am I missing something? Then, after the data has been manipulated on the client, I need to pass the rows back again so that the server side code can pick them up and process the updates.  I've seen a suggestion on here that a hidden text field is one way to do that.  Is it the best? Neither of my approaches seem to be at all elegant - and I suspect that I am missing something fundamental in ASP .NET AJAX! Thoughts welcome, Thanks, Nick

Infopath bug in windows 7 to convert datasource to data connection library in sharepoint?

Any ideas about this bug: Windows 7, infopath 2007, did not check in the data connection file when converting a data source? Also it did not set title and kept the file checked out so that you can not even update the items by SharePoint UI. I did everything successfully with Infopath 2007 on a windows xp machine. Is the OS related in this case? Thanks,
